1: 獲取recommended.yaml檔案

https://github.com/kubernetes/dashboard/blob/master/aio/deploy/recommended.yaml

2: 修改recommended.taml檔案

---
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  type: NodePort #增加
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30000 #增加
  selector:
    k8s-app: kubernetes-dashboard
---
#因為自動生成的證書很多瀏覽器無法使用，所以我們自己建立，註釋掉kubernetes-dashboard-certs物件宣告
#apiVersion: v1
#kind: Secret
#metadata:
#  labels:
#    k8s-app: kubernetes-dashboard
#  name: kubernetes-dashboard-certs
#  namespace: kubernetes-dashboard
#type: Opaque
---

3: 建立證書

mkdir dashboard-certs
cd dashboard-certs/
#建立名稱空間
kubectl create namespace kubernetes-dashboard
# 建立key檔案
openssl genrsa -out dashboard.key 2048
#證書請求
openssl req -days 36000 -new -out dashboard.csr -key dashboard.key -subj '/CN=dashboard-cert'
#自簽證書
openssl x509 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
#建立kubernetes-dashboard-certs物件
kubectl create secret generic kubernetes-dashboard-certs --from-file=dashboard.key --from-file=dashboard.crt -n kubernetes-dashboard

4：安裝dashboard

kubectl create -f ~/recommended.yaml

5：建立dashboard管理員

　vim dashboard-admin.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: dashboard-admin
  namespace: kubernetes-dashboard

kubectl create -f ./dashboard-admin.yaml

6：為使用者分配許可權

vim dashboard-admin-bind-cluster-role.yaml

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: dashboard-admin-bind-cluster-role
  labels:
    k8s-app: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: dashboard-admin
  namespace: kubernetes-dashboard

kubectl create -f ./dashboard-admin-bind-cluster-role.yaml

9:檢視使用者Token

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep dashboard-admin | awk '{print $1}')

10：開啟dashboard
